ROCK WOOL INSULATION

ROCK WOOL is an insulation material used for sound and heat insulation. Rockwool is also known as RB slab. Rockwool comes in various density and various thickness and can be delivered as per customer requirement
Used in
Duct insulation
Generator canopy insulation
soundproof room insulation
wall insulation
recording studio insulation

ROCKINSUL RB slabs are semi-rigid and rigid boards manufactured from stable rock fibers bonded with a minimum quantity of thermosetting resin binder. ROCKINSUL RB slabs are capable of withstanding extreme temperature up to 750 °C and are light weight, strong, resilient, easy to handle, and easy to cut to suit intricate shapes.STANDARD DIMENSIONSThickness(mm)Width(mm)Length(m)25 to 1256001.0 to 1.2STANDARD DENSITYDensity(kg/m3)Thickness(mm)4850 - 2006440 - 1508040 - 1259625 - 10012025 - 8014425 - 8016025 - 75* Non-standardized sizes and facing may be available on requestFACING TYPESROCKINSUL RB Slabs are available unfaced or with facing of ALG, glass reinforced Aluminium Foil/ Kraft paper laminate facing (FSK), Black Fiber Glass Tissue (BGT)WORKING TEMPERATUREFiber : Up to 750 °CFacing : 100 °CAt temperatures in excess of 230 °C a limited migration of binder may occur in the insulation in contact with the hot face. This does not impair the insulation performance.ACOUSTIC PERFORMANCEROCKINSUL RB Slabs achieve excellent acoustic performances (sound absorption coefficients, sound insulation, and impact sound isolation) when tested in accordance to various relevant ASTM standards. RB Slabs achieve Noise Reduction Coefficient (NRC) values up to 1, when tested in accordance to ASTM C423.FIRE SAFETY PERFORMANCEUnfaced ROCKINSUL RB Slabs are non-combustible when tested in accordance with IS 3144, BS 476 (part 4), ISO 1182 and ASTM E136 and are classified as Class A1, in accordance with European norms. Unfaced, FSK and ALG-faced RB Slabs have the following fire safety rating achievements:Class 1 surface spread of flame in accordance to BS 476 (part 7)Class 0 in accordance to the BS 476 (part 6 & 7) and to British Building Regulations.Surface burning characteristics in accordance to ASTM E84 / UL 723a: Fire Spread Index: Less than 25b: Smoke Developed Index: Less than 50

Rockloyd Slab - Resin Bonded, Rockwool Slabs
Rockloyd is a precisely engineered Resin Bonded Fibrous Insulation to offer maximum resistance to heat passage. Rockloyd Fibres are spun from selected rocks, melted at 1600°c and blended to a carefully adjusted chemical composition. Its centrifugally spun fibres have a diameter 1/20^th that of human hair which are felted using state of art Technology into bonded and cured slabs to optimum density and resilience.

Rockloyd is a precisely engineered Resin Bonded Fibrous Insulation to offer maximum resistance to heat passage. Rockloyd fibres are spun from selected rocks, melted at 1600°c and blended to a carefully adjustment chemical composition. Its centrifugally spun fibres have a diameter 1/20^th that of human hair which are felted using State of the Art Technology into bonded and cured mattress to optimum density and resilience. Over 25million sq.mts. of Rockloyd Insulation are in services in prestigious projects within the country saving millions of tones of fuel year after year.
Rockloyd, like all scientifically processed fibrous insulants is composed of fibres which are laid in the optimum configuration to offer maximum resistance to heat flow. To retain these exceptional properties up to the point of end-use, fibres are interlocked by lightly bonding them together using a thermosetting binder. Subsequently, matts are factory stitched to specified wire mesh using a continuous stitching machine to permit a ready-to-use configuration.
Salient Feature
Higher Thermal Performance, as it is made out of Rockwool and not slagwool.
Eliminated setting and sagging.
Longer Life, permitting reuse after removal during maintenance.
Environment Friendly, as there is no chicken feathering (Which normally pollutes the environment). It is ECO friendly to personnel due to the chemistry of fibres.
Uncontaminated, as manufacturing is totally a DRY Process.
Application Friendly, as it permits very fast installation.
Can feature Resistance to capillary if needed

Corrosion Protection
Rockloyd fibres, in the first place, are devoid of impurities like Halides (Chlorides & fluorides) and Sulphides which are commonly found in other materials such as Calcium Silicate. This is due to the fact that Rockloyd fibres are manufactured by a dry manufacturing process and its faint alkalinity actually fight against corrosive reactions. It meets various critical specifications including ASTM C 795 requirements where specified.
This feature is responsible for its exclusive selection for critical applications such as Nuclear Power plants, ship building and Railways coaches where corrosion resistance is of vital significance.
Fire Resistance
Incombustible when tested as per IS:3144 Melting point of fibres is above 1000°c (1825°F)
